Japan is bracing for what's expected to be a harsh heatwave on the 20th, with wide spread areas predicted to experience extreme heat. Health authorities are urging the population to be mindful of heatstroke, a potentially dangerous condition caused by prolonged exposure to such intense temperatures. Citizens are advised to stay hydrated, avoid unnecessary outdoor activities, and most importantly, to look out for each other, especially the elderly and those with predisposed health conditions.

Extreme summer heatwaves often cause a spike in heatstroke cases in Japan further straining the healthcare system in addition to the existing pressure due to the pandemic. People in Japan take such warnings very seriously as the nation has experienced deadly heatwaves in the past.

This is similar to heat advisories issued in hot climates in the US or in Europe when temperatures soar. However, Japan's quick and coordinated public health messaging is notable. In many Western countries, individual responses play a greater role, which can sometimes lead to slower reaction times.
